The kinetics of vacuum drying and rehydration in nitrogen of Wyodak-Anderson subbituminous, and Illinois 6 and Utah Blind Canyon high volatile bituminous coal samples have been studied at room temperature. Some samples were oxidized at room temperature. Several cycles of drying and rehydration were carried out on the same sample. The drying rates depended on particle size and moisture content of the sample. Several different mechanisms of moisture loss and rehydration were indicated by the kinetic data. The mechanism depended on particle size, coal rank, and degree of oxidation.
